Table 1 Admixture signatures from D-statistic (ABBA-BABA test). Only comparisons resulting in a D-statistic higher than 0.05 or lower than − 0.05 are shown (see Additional file 2: Table S10; Figures S8-S9 for more information). Non-sister taxa with signatures of considerable gene flow are marked in bold
